huh.. long title, let me explain the situation:
- there is an text edit box, user inputs some text, clicks away (or presses enter) - callback is invoked, which checks the input if it is OK. since the input is incorrect, an errordialog is showed asking user to correct his input. then
uicontrol(handleoftextedit)
is used inside the callback function to focus back to the text edit box.
- the problem now is: the user is not forced to correct the text edit box input, he can click away without being the callback invoked again after closing the error dialog box. i want the callback to be invoked if the user clicks away from the focused text edit box without correcting the previous incorrect value.

The callback is triggered only, if the string has been changed. This is not sufficient for your problem. In a similar case I delete the invalid string in the edit field.
